Normalization: The process used to minimize data redundancy and dependency in a relational database is known as normalization. The database table is divided into two or more tables and defines the relationship between those tables. If the modifications, deletion or updates occur in one table, the other tables in database get updated by just propagating it. In a relational database, the tables with no redundant data and less null values are considered as efficient table. This is because, having redundant data and more null values increases the storage space and wastage of memory is imminent. Null values cause a problem for data integrity and produces more error in the database. If the wasted storage space and null values which cause data integrity hazards are minimized, a highly optimized relational database can be designed. The project team should consider using normalization when designing the database, which is the best source to optimize data storage efficiently; this is because, it reduces the data storage space and provides data integrity. There are three types of normal forms. First normal form (1NF) Second normal form (2NF) Third normal form (3NF)

Normalization:

The process used to minimize data redundancy and dependency in a relational database is known as normalization.

The database table is divided into two or more tables and defines the relationship between those tables.

If the modifications, deletion or updates occur in one table, the other tables in database get updated by just propagating it.

In a relational database, the tables with no redundant data and less null values are considered as efficient table.

This is because, having redundant data and more null values increases the storage space and wastage of memory is imminent.

Null values cause a problem for data integrity and produces more error in the database.

If the wasted storage space and null values which cause data integrity hazards are minimized, a highly optimized relational database can be designed.

The project team should consider using normalization when designing the database, which is the best source to optimize data storage efficiently; this is because, it reduces the data storage space and provides data integrity.

There are three types of normal forms.

First normal form (1NF)

Second normal form (2NF)

Third normal form (3NF)

A cylinder of diameter 10 cm rotates concentrically inside another hollow cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise

Make the following game user friendly with GUI, with some simple graphics The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units. Cell Class: public class Cell { private boolean isWall; public Cell(boolean isWall) { this.isWall = isWall; } public boolean isWall() { return isWall; } public void setWall(boolean isWall) { this.isWall = isWall; } @Override public String toString() {…
